我如何从Json提取价值

Question

我从如下服务器获取响应字符串

{
  "name": "Json",
  "detail": {
    "first_name": "Json",
    "last_name": "Scott",
    "age": "23"
  },
  "status": "success"
}

我想获取名字的值。我怎样才能做到这一点？提前致谢。

看到此代码是我在应用程序中使用的代码

String data="{'foo':'bar','coolness':2.0, 'altitude':39000, 'pilot':{'firstName':'Buzz','lastName':'Aldrin'}, 'mission':'apollo 11'}";

我像这样找回

JSONObject json = (JSONObject) JSONSerializer.toJSON(data);        
    double coolness = json.getDouble( "coolness" );
    int altitude = json.getInt( "altitude" );
    JSONObject pilot = json.getJSONObject("pilot");
    String firstName = pilot.getString("firstName");
    String lastName = pilot.getString("lastName");

    System.out.println( "Coolness: " + coolness );
    System.out.println( "Altitude: " + altitude );
    System.out.println( "Pilot: " + lastName );
